Description
Kondensator, der nach Art eines elektrischen Transformators mit oder ohne Eisenkern sowie mit Wicklungen ausgestattet ist -Es. ist bereits bekannt geworden, kondensatorartige Apparate in -der Weise zu bauen, daß,die Sekundärwicklung eines Transformators entweder auf einen dielektrischen Kondensator, z. B. ein Kabel, geschaltet oder so eingerichtet wird, daß sie aus Bändern, besteht, welche an sich gegeneinander eine Ladung annehmen können.Capacitor, which is like an electrical transformer with or without an iron core as well as equipped with windings -It. has already become known to build capacitor-like apparatus in such a way that, the secondary winding of a Transformer either on a dielectric capacitor, e.g. B. a cable switched or so arranged that it consists of ribbons, which are intrinsically against each other can accept a charge.
Das Wesen des Erfindungsgegenstandes möge an Hand der Abb. z beschrieben werden. Durch -den Buchstaben a sei -der Kern eines Wechselstrom- oder Drehstromtransformators dargestellt. Auf -diesem Kern sitzt, wie bei jedem Transformator, eine Primärwicklung b, welche an den in Betracht kommenden Betriebsstromkreis angeschlossen wird. Außer dieser Primärwicklung ist noch eine aus mehreren Teilen bestehende Sekundänvicklung vorhanden. Der Übersichtlichkeit wegen sind nur drei Teile dieser Wicklung gezeichnet, nämlich c" c. und c3. Jedes dieser Wicklungs.systeme besteht aus einem Zylinder aus Isolationsmaterial mit einer einlagigen Drahtwicklung. Der Wicklungssinn der Wicklung ist bei den ungeraden Zylindern umgekehrt wie bei den geladen. Infolgedessen entsteht in einem bestimmten Augenblick z. B. in den Zylindern cl und c" ein Ladestrom, der dem in dem Zylinder c" entstehenden Ladestrom entgegengerichtet ist. Das zwischen den Wicklungen befindliche Isolationsmaterial wird daher als Dielektrikum geladen- In der nächsten Halbperiode des Wechselstromes kehrt sich,die Stromrichtung in beiden Wicklungssystemen um. Die hin und her fließenden Ladeströme erzeugen ib rerseits ein magnetisches Feld und übertragen sich dadurch auf ,die primäre Wicklung. Der Strom in der Primärwicklung wird sich daher aus dem Magnetisierungsstrom und dem Ladestrom zusammensetzen. Da diese beiden entgegengesetzt sind, kommt für den resultierenden Strom ihre Differenz ein Betracht und, wenn die Elektrisierungsleistung groß genug ist, dann wird die Magnetisierungsarbeit verschwinden. Der primäre Strom arbeitet dann wie in einem Kondensator. Uni diese Kondensatorwirkung möglichst hervorzukehren, ist nur erforderlich, daß die Zahl der Zylinder genügend. groß gemacht wird und daß sowohl die Windungszahl wie :der Abstand so gewählt sind, daß eine möglichst vollständige Ausnutzung des zwischen den Zylindern liegenden Isolationsmaterials gewährleistet ist. Die ganze Apparatur kann, in ein geeignetes Dielektrikum, wie Luft, Druckluft, öl, oder irgendein anderes Material gesetzt werden. Ebenso können die Wicklungen cl, c2, c@ usw. in irgendein festes Material, z. B. Hartpapier oder Kabelmasse, eingebettet werden.The essence of the subject of the invention may be described with reference to Fig. Z will. By -the letter a is -the core of an AC or three-phase transformer shown. As with every transformer, there is a primary winding on this core b, which is connected to the relevant operating circuit. Except This primary winding is still a secondary winding consisting of several parts available. For the sake of clarity, only three parts of this winding are drawn, namely c "c. and c3. Each of these winding systems consists of a cylinder made of insulation material with a single-layer wire winding. The winding sense of the Winding is reversed for the odd cylinders as for the loaded ones. Consequently arises at a certain moment z. B. in the cylinders cl and c "a charging current, which is opposite to the charging current arising in the cylinder c ". The between The insulation material in the windings is therefore charged as a dielectric. In the next half cycle of the alternating current, the direction of the current is reversed in both Winding systems. The charging currents flowing back and forth generate on the other hand a magnetic field and thereby transferred to the primary winding. Of the Current in the primary winding is therefore made up of the magnetizing current and the Assemble the charging current. Since these two are opposite, the resulting comes up Electricity takes their difference into account and, if the electrification power is large enough then the work of magnetization will disappear. The primary stream is working then like in a capacitor. Uni to bring out this condenser effect as much as possible, it is only necessary that the number of cylinders is sufficient. is made big and that both the number of turns and: the distance are chosen so that one as possible full utilization of the insulation material between the cylinders is guaranteed. The whole apparatus can, in a suitable dielectric, such as Air, compressed air, oil, or any other material. Likewise can the windings cl, c2, c @ etc. in any solid material, e.g. B. hard paper or Cable mass, to be embedded.
Gemäß der Erfindung werden also Wicklungsteile uls Belege eines Kondensators ausgebildet und,die Ladungen nicht durch direkte Zuführung des Stromes, sondern durch elektroma:,gnetdsche Induktion in diesen Wicklungsteilen hervorgerufen. Diabei kann grundsätzlich die Eigenkapazität noch durch Zusatzflächen vergrößert werden. In Abb. 2 ist gezeigt, wie durch seitliche Verlängerungen aus Metallblech dl, d@ und d. dieser Kapazitätszluwachs bewirkt wird.According to the invention, therefore, winding parts become evidence of a capacitor formed and, the charges not by direct supply of electricity, but caused by electro-magnetic induction in these winding parts. Doing this In principle, the own capacity can be increased by additional areas. Fig. 2 shows how lateral extensions made of sheet metal dl, d @ and d. this increase in capacity is effected.
Die Form der sekundären Spulen kann. beliebig gewählt wenden. In Abb. 3 :ist z. B. eine gleichwertige Anordnung mit flachen Spulen e" e2, e3 usw. gezeichnet.The shape of the secondary coils can be. turn as desired. In fig. 3: is e.g. B. an equivalent arrangement with flat coils e "e2, e3, etc. drawn.
Es ist nicht nötig, unbedingt einen Eisenkern zur magnetischen Kopplung zu verwenden. Es genügt vielmehr für viele Zwecke, namentlich für Stromkreise mit hoher Frequenz, wenn das Luftfeld der Arbeitswicklung zur Übertragung benutzt wird. In diesem Falle kann die Kapazitätswicklung sowohl innerhalb wie außerhalb der Spule a in Abb. q. liegen.It is not necessary to have an iron core for magnetic coupling to use. Rather, it is sufficient for many purposes, especially for electrical circuits high frequency when the air field of the working winding is used for transmission. In this case, the capacitance winding can be both inside and outside the coil a in Fig.q. lie.
Es ist selbstverständlich, daß einzelne Punkte,der sekundären Wicklungsteile an das Erdpotential oder irgendein anderes Potential angelegt werden können. Ebenso kann der Apparat für mehrere Phasen ausgeführt werden.It goes without saying that individual points of the secondary winding parts can be applied to the earth potential or any other potential. as well the apparatus can be run for several phases.
